British Motor Show - Lexus LF-A supercar

Behold the Lexus LF-A, a supercar that remains a concept car despite being launched in 2005 and contesting this year's Nurburgring 24-Hour race in front of 100,000 fans.

Powered by a mid-mounted 500bhp 5.0-litre V10 engine, the car has a top speed of 200mph. It oozes high-performance styling, too, with much of its body made from aluminium and carbonfibre to save weight.

Even the two radiators to cool the engine are rear-mounted to aid weight distribution. They feed air through ducts just above the rear wheelarches onto a rear spoiler, which is activated at high speed to create more downforce and increase grip.

So will it ever make production? Almost certainly - Lexus has invested a lot of time and money in developing the car to such a high level.

The question of when remains, though. Frustratingly, Lexus won't commit to a date.

IS-FLexus will show its high-performance IS-F at the show.

The car is powered by a 417bhp 5.0-litre V8, which takes it from 0-62mph in 4.8 seconds.

It also features an eight-speed semi-automatic gearbox, high-performance brakes and 19-inch alloy wheels.

It's also lower and lighter than the IS compact executive on which it is based, and features styling changes that include a deeper front spoiler, wider wheelarches and side vents.

Hybrid powerLexus is also using the show as an opportunity to show off its range of hybrid vehicles.
